The function is widely used in PHP applications, so running them inside of a shared folder is impossible. This can be tested by installing PHP and executing the following commands, while inside a shared folder: ---------------- > echo text > test.txt > php -r ""var_dump(is_readable('test.txt'));"" bool(false) ---------------- Same code works fine inside any other folder in the guest system. Or inside a folder, mounted as a usual network share. Also, while the file is mistakenly reported as not readable, PHP still can read it via any of its file utility functions, e.g. via ""file_get_contents('text.txt');"" I used VirtualBox 4.2.10, Guest Addtions 4.2.10, PHP 5.3." defect closed guest additions VirtualBox 4.2.10 obsolete phpunit, is_readable, guest additions, shared folder Windows all
